What's a Twitter "short code"?

These are phone numbers that are used by Twitter to help you access your Twitter account via SMS on your phone. You can text message your Tweet to your respective code/number and it will post to your Twitter profile. Different countries use different codes. Find your country's short or long code.

Can I update Twitter from my phone but not receive other people's updates? And vice versa?

Additionally, you can set your sleep settings in your web profile to silence mobile updates for certain periods of every day.

Why am I receiving two sets of notifications on my device?

If you have a smartphone that supports an official Twitter app and are receiving two sets of notifications (one through SMS and one through the app's push notifications) you may want to disable your SMS notifications. To do this, send OFF to your Twitter short code. Now you will only receive one set of notifications!

I don't live in the US. How do I use Twitter on my phone?

We have short codes for many countries and carriers - texting one of these will allow you to Tweet via SMS. If your country is not listed there, you might want to use our one-way long code to post content to Twitter. Please note that all subscribers (even in the UK) may be charged international message rates.

You can also go to our mobile website, mobile.twitter.com from your phone's browser no matter where you are in the world (as long as you have cell reception on your smartphone!).
